[0003] In the prior art, to accommodate the positioning of square frames with multiple right-angled sides, matching strip clamps are usually set for clamping. For example, patent CN215942205U discloses a quick-fixing fixture for processing square frame workpieces. Specifically, it uses the operation of a hydraulic rod to drive a pair of limiting clamps to move, adjust the vertical distance between the limiting clamps and the work platform, and clamp the workpiece through the limiting clamps and the work platform. However, although using a pair of limiting clamps can clamp and fix the workpiece, the fixing direction is unidirectional. More importantly, it cannot meet the processing operations such as multi-sided grooving of square frame workpieces.

[0004] Based on the above description, there is an urgent need for a positioning device for square frame workpieces that can be fixed and facilitates multi-sided processing. Utility Model Content

[0028] In this embodiment, multiple pressing components 2 are spaced and pressed onto the four sides of the positioning base plate 1, thereby stably installing the positioning base plate 1 onto the machine tool. According to the processing requirements, multiple positioning components 3 are used to position each side of the square frame workpiece onto the positioning base plate 1. Furthermore, the four corners of the workpiece can be positioned, and they are arranged opposite to the pressing components 2. This ensures the stability after positioning, does not affect the subsequent processing of the mounting holes and assembly slots on the sides of the workpiece, and ensures the uniformity of the force on the workpiece, thereby ensuring the processing accuracy.

[0029] In this embodiment, a recessed mounting groove 1 can be provided in the middle of the positioning base plate 1 to limit the square frame workpiece, thereby improving the positioning accuracy, reducing the number of positioning components 3, and improving the positioning efficiency.
